Real-time communications services will be one of the most promising applications on the Internet. Real-time traffic usually utilizes a significant amount of resources while traversing through the network. To provide guaranteed service for delay-sensitive real-time applications, both resource reservation and effective traffic control are necessary. The resource reservation protocol (RSVP) was de...

–Based on end-to-end delay measurements of IP probe-packets over a Þxed path obtained from RIPE NCC, we model the stochastic part of the delay and propose statistical methods to analyse the data. The Internet traffic on the Þxed path interferes with the IP probe-packets. This is modeled as an alternating on/off renewal process. On top of the delay caused by Internet traffic, the IP probe-packet...

Modern train control systems rely on a dedicated radio network for train to ground communications. A number of possible alternatives have been analysed to adopt the European Rail Traffic Management System/European Train Control System (ERTMS/ETCS) control system on local/regional lines to improve transport capacity. Among them, a communication system based on public networks (cellular&satellite...

This letter presents an experimental evaluation of end-to-end delay in Sigfox networks, considering measurements from the transmitter to server. We carried out two types cases. The first was a static experiment with typical delivery time ranging between 2.5 and 4.5 seconds, 100% rate. second considers mobility, experiments mostly rural environments which is inside car. In this case, we observed...

In this paper, we developed a new customizable low energy Software Defined Networking (SDN) based Internet of Things (IoT) platform that can be reconfigured according to the requirements target IoT applications. Technically, consists set cost and efficient single-board computers, which are interconnected within network with software defined configuration. The proposed SDN switch is deployed on ...
